There was a technical issue affecting all outgoing emails and that prevented our registrations from completing and sending out activation emails. The error has now been resolved and protections have been put in place to prevent it from happening again. This was a very unusual error and likely won't happen again.

The server was taken down today for an extensive hardware analysis. We discovered an additional issue with the power supply and replaced it. Combined with the recent cooling fix, we should have a very stable server going forward (no more random crashes). This is an important foundation for the upcoming patch.
